Definitions

  • the present invention relates to a tow assembly for agricultural machines.
  • the present invention relates to a tow assembly
  • a tow assembly comprising a frame which is fixed to an agricultural machine, presents a substantially U-shape with concave side pointing up, and includes two vertical rods substantially parallel to each other and connected to each other through a fixed horizontal cross-piece fitted with a first hooking pin for coupling an agricultural equipment to the agricultural machine itself.
  • the tow assembly further comprises a vertical guide obtained along the two vertical rods and engaged in a sliding manner by a slide of a tow hook fitted with a second hooking pin for coupling an agricultural equipment to the agricultural machine.
  • a tow assembly for agricultural machines is provided according to the present invention as set forth in the appended claims.
  • number 1 indicates, as a whole, a tow assembly for known and not illustrated agricultural machines.
  • the tow assembly 1 comprises a frame 2 which is fixed to an agricultural machine (not illustrated), extends around a power takeoff 3 of the agricultural machine itself and comprises, in turn, two vertical rods 4 parallel to each other that extend in a substantially vertical direction 5 and are connected to each other through a pair of cross-pieces 6 substantially parallel to each other and to a horizontal direction 7 that crosses direction 5 itself.
  • Each vertical rod 4 is limited on its sides in direction 7 by two side faces 8, 9 substantially parallel and opposite to each other, and where the face 8 is facing the face 8 of the other vertical rod 4.
  • Each vertical rod 4 presents a longitudinal groove 10 which is obtained on its relative face 8 parallel to direction 5 and is fitted with a plurality of holes (not illustrated) which are obtained on the vertical rod 4 parallel to direction 7, are aligned with each other in direction 5, and are each aligned with a relative hole (non illustrated) in the other groove 10 in direction 7 itself.
  • the two grooves 10 define a guide 11 apt to receive in a sliding manner a slide 12 of a first tow hook 13 of known type, further comprising a first hooking pin 14 led by the slide 12 to enable the hooking of known and not illustrated agricultural equipment to said agricultural machine (not illustrated), and a pair of locking pins 15 opposite each other which extend in direction 7, protrude outside the slide 12 in direction 7, and are mobile, with respect to the slide 12, in direction 7 itself between an extracted locking position ( figure 1 ), in which the pins 15 engage respective holes (not illustrated) of the relative vertical rods 4, and a backward unhooking position (not illustrated).
  • Each vertical rod 4 further presents a dovetail guide 16 which is obtained on its relative face 9 parallel to direction 5 and cooperates with the guide 16 of the other vertical rod 4 to support a second tow hook 17 in a sliding manner.
  • the tow hook 17 comprises two brackets 18 parallel to each other which extend in direction 5, each matched in a sliding manner to a relative guide 16, and connected to each other by an end cross-piece 19 that extends between the brackets 18 parallel to direction 7, and is fitted with a second hooking pin 20 projecting upwards from the cross-piece 19 in direction 5 to enable the hooking of known and not illustrated agricultural equipment to the said agricultural machine (not illustrated).
  • the tow hook 17 is mobile between a raised position ( figure 1 ), in which the cross-piece 19 and the pin 20 cooperate with a locking element 21 protruding from the lower cross-piece 6 to prevent said agricultural equipment (not illustrated) from disengaging the pin 20 itself, and a lowered position (not illustrated), in which the cross-piece 19 and the pin 20 are arranged at a distance determined by the element 21 to enable the hooking and unhooking of said agricultural equipment (not illustrated) respectively to and from the pin 20 itself.
  • the tow hook 17 is moved between its lowered and raised positions by two actuator cylinders 22 which are fixed to the frame 2 opposite the upper cross-piece 6 in direction 7, extend in direction 5, and present respective exit bars 23 connected to the cross-piece 19.
  • the raised position of the tow hook 17 is ensured thanks to a security device 24 comprising a support shaft 25 mounted rotatingly through the frame 2 to rotate around its own longitudinal axis 26 parallel to direction 7, and a pair of even hooks 27 parallel to each other, which are mounted on the shaft 25 orthogonal to direction 7, protrude downwards from the shaft 25, and are normally maintained in a hooking position (illustrated as an unbroken line in figure 3 ) by a pair of springs 28 placed between the lower cross-piece 6 and the hooks 27 themselves.
  • a security device 24 comprising a support shaft 25 mounted rotatingly through the frame 2 to rotate around its own longitudinal axis 26 parallel to direction 7, and a pair of even hooks 27 parallel to each other, which are mounted on the shaft 25 orthogonal to direction 7, protrude downwards from the shaft 25, and are normally maintained in a hooking position (illustrated as an unbroken line in figure 3 ) by a pair of springs 28 placed between the lower cross-piece 6 and the hooks 27 themselves.
  • the two hooks 27 are first moved to a release position (illustrated as a broken line in figure 3 ) by means of a bar 29 fixed on the cross-piece 19 parallel to direction 7, and then engage in a sliding manner respective slits 30 parallel to each other, which are obtained through the cross-piece 19 in direction 5 and extend below the bar 29 itself.
  • the hooks 27 are moved by the springs 28 in their hooking position for the bar 29 ( figure 3 ) and cooperate with the cylinders 22 to ensure the proper maintenance of the tow hook 17 in its raised position.
  • the hooks 27 are directly moved by the operator into their release position through a tie-rod (not illustrated) connected to a shaft 25 and mounted inside the driving cab of said agricultural machine (not illustrated).
  • the tow assembly 1 is also fitted with a protective casing 31 which is mounted on the frame 2 between the two vertical rods 4 and is selectively moved between an operating position ( Figure 1 ), in which the casing 31 is arranged transversely to direction 5 to prevent access to the power takeoff 3 and enables the use of the tow hook 17, and a resting position (not illustrated), in which the casing 31 is arranged on the outside of the guide 11 to enable the use of the tow hook 13.
  • the structure of the frame 2 therefore ensures access to and protection of the power takeoff 3, while the tow assembly 1 presents such an overall size as to enable the use of a three-point equipment fastening.
